摘要
为了正确评价和合理开发荆泉岩溶水资源,采用MODFLOW软件,建立了荆泉岩溶水系统地下水流数值模型,利用地下水管理软件(GWM),将地下水流数值模型与最优化模型耦合,并以开采量最大化为目标,以不低于该地区防止岩溶地面塌陷所限定的控制水位为约束条件,根据荆泉地区1991~2016年的降雨资料,确定预测模型的降雨补给条件,在此基础上,对荆泉水源地地下水开采潜力进行了模拟评价,进而给出荆泉水源地最优开采量,为荆泉水资源开发管理提供了技术支撑。
In order to correctly evaluate and rationally develop the karst water resources in Jingquan,the groundwater flow numerical model of Jingquan karst water system is established by using MODFLOW simulation software.The groundwater flow numerical model is coupled with the optimization model by using the optimization model software"Ground-Water Management(GWM)".The objective function is to maximize the exploitation amount,and the constraints are that the water level is not lower than the control level which is determined to prevent karst ground collapsed.Based on the rainfall data from 1991 to 2016 in Jingquan area,the rainfall recharge condition of the optimization model is determined.On this basis,the groundwater exploitation potential of Jingquan water source area is simulated and evaluated,and then the optimal exploitation scheme of each mining well is obtained.Thus,it provides technical support for development and utilization of water resources in Jingquan area.
